Kerbal Space Program

I just noticed while building an artistic structure in the VAB (for a mission I'm creating) that when using physics warp, things tend to pull downward on parts that can bend. My understanding of the physics warp is that the animations get faster, the frequency of calculations on parts might not be as often for each game time period, but the mass of objects shouldn't change so neither should their gravitational pull. I built this craft just to test and demonstrate for you. To reproduce, just load the craft on the launch pad, then watch as you increase up to x4 warp.
